CARBURETER.

SPECIFICATION forming part of Letters Patent No. 716,452, dated December 3, 902- Application filed January 20, 1902. Serial No. 90,581. (No model.)

To (tZZ whom it may concern.-

Be it known that I, GEORGE A. MANwAn- ING, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Carbureted-Air or Gas Making Machines, of which the. following is a specification.

The object of my invention is to provide an automatic air-carbureting or gas-making machine which shall make a burning-gas by carbureting air with What is commonly known as naphtha or gasolene. My device is not limited to the use of the petroleum products, as it would work equally well with alcohol, ether, or other volatile fluids whose vapors are inflammable. In this type of machine one of the most important features is to secure a gas or mixture of practically constant richness-that is, a gas which will yield upon burning a constant number of thermal units. When using petroleum products, the air being driven through the liquid first absorbs the most readily-volatile portion of the fluid, leaving behind that portion which is heavier and less soluble in air, so that the proportion of air flowing through the liquid must be increased to take up and mix with a constant quantity of vapor. For this purpose the adjustable device is introduced in my invention between valve-handles P and X the operation of which is described hereinafter. This adjustable device is set when the machine begins operation and is changed from time to time by lengthening or'shortening the connection between the two valve-handles, so as to force more and more air to flow through carbureter F as the gas becomes less rich by reason of the exhaustion of the more volatile portions of the liquid.

The invention consists of the details of construction substantially as hereinafter described, and shown in the claims and drawings, respectively.

Reference is made to the accompanying drawings, which form part of this specification, and in which similar letters refer to and indicate corresponding parts in all figures.

Figure 1 is a graphic View, partly cross-sectional, showing the interconnection and operation of the various parts. Fig. 1: F shows an air-carbureter of any suitable construction. Fig. 1: Gis a pipe connection between the carbureter F and the gasometer-bell K. Fig. 1: K is a gasometer-bell for storing the carbureted air or gas ready for consumption. Fig. 1: L is an arm or bracket rigidly fastened to the movable storage-chamber or gasometer-bell K, which arm or bracket moves the valve-rod O by pressing against the collars M or N as the gas-bell rises and falls. Fig.1: M and N are either fixed or adjustable collars on valve-rod O, which enable the valverod to be moved up or down by means of the arm L as the gas-bell rises and falls. Fig. 1: O is a valve-rod connecting with the valvehandle P Fig. 1: P is a valve controlling the flow of air coming from pump Q, and going to carbureter F through pipe D also controlling the air going to the gas-bell through valve X, pipe J, and check-valve H. Fig. 1: Q shows an air pump or compressor of any suitable type, in this case being operated by water-pressure. Fig. 1: R is the waterinlet to the pump. Fig. 1: R is the water outlet or waste from said pump. Fig. 1: W is an opening in the sliding guide-tube K to admit carbureted .air to the storage-space of gas-bell K. Fig. l: X is a by-pass valve which can by the operation of the tappet E be made to open more or less every time valve P opens, so permitting part of the air coming from pump Q to be short-circuited and pass directly into the gas-bell without having to go first through the carbureter F. Fig. 1: D is a pipe leading air from the pump Q to the carbureter F. Fig. 1: E is a sliding block or tappet rigidly fastened to rod A and sliding on rod B, so operating valve X by tapping against collars O and O", which are rigidly but adjustably fastened to rod B. Fig. 1: J is a pipe leading from valve X to carbureted air or gas pipe G. Fig. 1: II is a check- Valve in carbureted-air or gas pipe, so that when carbureter F is to be filled with a volatile liquid through filling-plug G the gas or carbureted air in the gas-bell cannot flow back through carbureter, and so escape. Fig. 1: l? and X are valve-handles operating valves P and X. Fig. 1: K is the tank in which the gasometer-bell K operates. Fig. 1: K K are sliding guide-tubes rigidly fastened to bell K and which guide it in its motions by sliding over the inlet and outlet pipes J 2 and J respectively. Fig. 1: O is the normal water-level in gasometer-tank X Fig. 1: Y is a hole in guide K permitting the gas or carbureted air to pass from the bell into and through service-pipe J and so to connection to house-pipe Z.

Fig. 2: O and O are adjustable collars rigidly fastened on and to rod B and against which the block or'tappet ll) works to operate valve-handle X Fig. 2: A and B are rods connecting valve-handles P and X by means of the operation of tappet E The operation of the machine is as follows: When the water is turned on to pump Q, it starts pumping and delivering air through valve P. This air is divided into two portions, one part going by way of pipe D to and through a suitable carburetor F,, thence through pipe G, check-valve H, pipe J into sliding tube K ,out of hole W,and into gas-bell K,where it remains ready for use. The second portion of air goes directlythrough valve X, pipe J, check-valve H, and so into gas-bell K, as before. The proportion of air going through the carbureter and the portion going direct to the bell will adjust themselves in proportion to the extent to which valve X is opened by the operation of the tappet or block E", which in turn is operated by the opening of Valve P. The size of opening through Valve X is regulated as required by the changing of the position of the collars O and C on the rod B. As collar 0 is set higher up on rod B the tappet E pushes the valve-handle X lower down, when the bell falls, so obtainingalargcr opening through valve X, and vice versa. Instead of changing the position of collar G a short nipple or other obstruction may be placed by any convenient means or manner between collar 0 and tappet E thus accomplishing the same end of varying the proportion of air which shall fiow through the carbureter and direct into the bell without passing through the curbureter. When these valves P and X are opened by the falling of the bell K and arm L, operating against the collar N and moving rod 0, the pump automatically starts delivering air faster than the mixture is drawn from the 'bell for use, so causing the bell to rise until arm L, operating against collar M, lifts rod 0, which in turn raises handles P and X thus shutting 01f the air and stopping the pump by stalling it. By these means an intermittent action is obtained. As the gas or carbureted air is consumed the bell again falls and repeats the operation as above described.

Having thus fully described my invention, what I desire to secure by Letters Patent is- 1. In a carbureted-air or gas machine, an air pipe or conduit leading to one or more carbureters, said air-pipe having a valve or shut off device therein; a short-circniting pipe leading from said air pipe or conduit to the return-conduit leading to the gas-storage chamber, said short-circuit pipe or conduit having therein a valve or shut-off device, the valve in the air-pipe being adjustably connected to the valve in the short-circuitin g device, said valves and adjustable connection being operated by the movements of the movable storage-chamber, or.gasometer-be1l.

2. In acarbureted-air or gas making device, the combination of a movable gas-receptacle, and an air pump or compressor connected with two air-valves, the said valves being interconnected by means of an adjustable device and operated by said movable gas-receptacle, said adjustable connection being so arranged as to permit of one valve being opened or closed, more or less than the other, by the same movement of the gas-storage chamber, all so connected as to be mutually operative, substantially as and for the purpose set forth.

3. In a carbureted-air or gas machine, or device; the combination of a movable gasstorage chamber, an air-pump, or compressor; an air-valve in the pipe system between said pump or compressor, and the air-carbureting device; an air-valve in a by-pass pipe between the main air-line, and the pipe returning from the air-carbureting device to the gasstorage space; said two valves being interconnected with an adjustable connection, enabling said connection to be so adjusted as to permit more or less air according to the adjustment to short-circuit and go direct to the gas-storage chamber without having to pass through the air-carbureting device.

4. In an air-carbureting or gas machine, or device, the combination of a movable gasstorage chamber, an air pump or compressor, an air-valve in the pipe system between said pump or compressor and the carbureting device, a return-pipe between the carbureting device and the gas-storage chamber, an air by-pass pipe between the air-pipe leading to the carburetor and the pipe returning from the carburetor to the movable gas-storage chamber, said by-pass having a valve placed therein, adjustably connected to or with the main air-valve between the pump or compressor and the carbureter.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses,this 20th day of December, 1901.
